From Wikipedia, the free encyclopaedia

energy is the radiant light and heat from the Sun that has been
harnessed by humans since ancient times using a range of ever-evolving
technologies. Solar radiation along with secondary solar resources such
as wind and wave power, hydroelectricity and biomass account for most of
the available renewable energy on Earth. Only a minuscule fraction of
the available solar energy is used.
Solar power technologies provide electrical generation by means of heat engines or photovoltaics. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favourable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. |

The Benefits of Solar Power The sun produces massive amounts of heat that are transmitted down to the earth's surface. When the sun's rays reach the earth's surface the intensity of the heat directly from the sun is not as hot because some of the heat is rerouted before it reaches the earth's atmosphere. When the sun is hot and it is summer time we think that it couldn't get much hotter as the mid day sun makes your run for shade, but it can get hotter if it wasn't rerouted. Solar power can be hot enough to power machinery and that is exactly what was discovered over one hundred years ago when a man working on machinery wondered if steam from the heat of the day could be used to power machinery. He was right and thus began a new form of production, heat and electricity. Today solar power is being used all around the world. The solar power is being concentrated into a solar source where the heat is used in a variety of ways. We still rely on our way of heating and powering our homes but in the future it may all be powered by the sun. It is cost effective to use solar power as the only expense you have is in your solar source. In order to use solar power you will need to have something that can attract the sun and allow the heat to be concentrated where it can stay warm for a long period of time. This is fairly easy when you consider all the knowledge and resources that we already have access to. When you use solar power for heating and power electricity you cannot go wrong. Solar power is entrusted in space shuttles as they know that this will help produce the most efficient energy with the least amount of complications. The solar panels are faced toward the sun at all times in order to be able to power the shuttle efficiently. There are fewer problems from solar power than with other methods. Even though there are days that there are clouds in the sky and rain, snow or other weather, it is still possible to produce enough heat in your solar source to create enough energy to last until the sun can come back down. |

power is in our future we need to be ready for it. Right now solar power
is only being used by those who are more aware and worried about our
earth's atmosphere when it is a concern that we should all be worried
about.
We can learn a lot from the past and the way that solar power was used. Every minute of the sunlight was used doing everything that needed done because after the sun went down there was no more light. I don't think we could do that now. Solar power has so many benefits for us that we don't realize all of them and how it is more efficient to use the solar power than other ways.
